across the plate. In place of this appendage, in the larger female ex- 

 ainiued, there is a small ovate lamella with a narrow fold along its inner 

 edge, while in the smaller female there is a minnte styliform process. 

 The inner ramns of the second pleopod of the male is very slender 

 and less than a fourth as long as the outer, but bears on the anterior side 

 near the base an approximately round chitinons plate about ;>i""" in 

 diameter with the inner and distal edges armed with short setie. The 

 Inner ramus of the second pleopod of the female is similar, but wants 

 the chitinous plate. The inner rami of the third, fourth, and fifth pairs 

 of pleopods in both sexes are very slender, but increase successively 

 in length to the fifth pair where they are only a little shorter than the 

 outer rami. 



The number and arrangement of the branchiaj are indicated in the
